We reviewed 15 572 Australian species-level records of the marine planktonic dinoflagellate Tripos Bory (formerly Ceratium Schrank, a genus now restricted to freshwater species). The genus is represented by over 50 species and numerous varieties and forms in Australian tropical, subtropical and temperate marine waters and the Southern Ocean. There exists considerable plasticity in the morphology of many species, which has confounded species delimitations and created uncertainty around their spatial distributions. We newly illustrate by light and electron microscopy the rarely reported Tripos hundhausenii (Schröd.) Hallegr. & Huisman comb. nov. first described from the Arabian Sea, but increasingly being observed in Sydney coastal waters. A large number of Tripos species are widely distributed in temperate, subtropical and tropical waters and their distributions have remained remarkably stable in Australian waters over the past 60–80 years. By contrast, we identified a narrow group of warm-water species, including T. belone (Cleve) F.Gómez, T. cephalotus (Lemmerm.) F.Gómez, T. dens (Ostenf. & E.J.Schmidt) F.Gómez, T. digitatus (F.Schütt) F.Gómez, T. gravidus (Gourret) F.Gómez, T. incisus (G.Karst.) F.Gómez, T. paradoxides (Cleve) F.Gómez and T. praelongus (Lemmerm.) F.Gómez, that are commonly encountered off Sydney, rarely found down to Eden and Batemans Bay or Bass Strait, but occasionally occur as far south as King Island and Maria Island, Tasmania. These rare tropical Tripos species are carried southward by the East Australian and Leeuwin Currents and deserve careful attention in monitoring for future range expansions, changes in seasonality or upwelling or incursion of deep tropical waters.","PeriodicalId":55416,"journal":{"name":"Australian Systematic Botany","volume":"33 1","pages":"392 - 411"},"PeriodicalIF":1.6,"publicationDate":"2020-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1071/SB19043","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46309883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These subspecies were originally segregated primarily by differences in leaf size and shape and the number of flowers produced, but a critical examination of herbarium specimens found that these features were highly inconsistent within taxa. These features were also found to be highly variable over time and space within populations of living plants. The distribution patterns, habitat preferences and flowering times of these taxa were found to overlap, even for subspecies brevifolius and orientalis, which occupy the northern and eastern limits of the distribution of this species. Eriochilus dilatatus subsp. magnus and subsp. multiflorus were shown to be synonyms of subsp. dilatatus, whereas subsp. undulatus and subsp. orientalis are synonymised under subsp. brevifolius. As a result of this study, the two recognised subspecies are subsp. dilatatus and subsp. brevifolius, which can be readily separated by plant height, flower numbers and leaf morphology, except for a few intermediate plants where ranges overlap. New keys and descriptions to these taxa are provided. The reasons for previous taxonomic confusion in this group and in many other Western Australian orchids are discussed and research approaches to resolve these issues are suggested.","PeriodicalId":55416,"journal":{"name":"Australian Systematic Botany","volume":"33 1","pages":"329 - 345"},"PeriodicalIF":1.6,"publicationDate":"2020-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1071/SB19024","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48618620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the aim to solve long-standing problems of taxonomic delimitation within the E. obovatus species complex (E. obovatus G.Don, E. arnhemicus F.Muell., E. sp. Mt Bellenden Ker (L.J.Brass 18336) Qld Herbarium and E. coorangooloo J.F.Bailey & C.T.White), diversity and relatedness were assessed using a combined population genetics and morphometric approach among 181 and 102 individuals respectively. Simple sequence-repeat (SSR) markers were analysed with clustering methods, analysis of molecular variance (AMOVA) and STRUCTURE. The morphometric data were analysed using cluster and classification and regression tree (CART) methods. The morphometric and genetic analyses together resolve discrete groups corresponding to E. arnhemicus, E. coorangooloo, E. obovatus and E. sp. Mt Bellenden Ker. Elaeocarpus arnhemicus is clearly distinct from all other entities on most of the morphometric and genetic analyses. By contrast, E. sp. Mt Bellenden Ker and E. obovatus were not clearly separated from each other in many morphometric analyses, but can be distinguished clearly by the strongly curved pedicels in early bud and hairy ovary, and, to a lesser extent, by the frequent occurrence of two racemes per axil and cuneate leaf bases, and on the results of the genetic analyses. Elaeocarpus coorangooloo exhibits considerable genetic admixture with the other entities, but it is morphologically distinct. SSR profiles suggested that E. arnhemicus and E. obovatus may be tetraploid, whereas the other entities are diploid. This study has clarified the taxonomic limits of the currently recognised species E. arnhemicus, E. obovatus and E. coorangooloo and supports recognition of E. sp.

A molecular phylogeny to test the monophyly of Nephelolejeunea by using previously published nrITS, rbcL and trnL–F sequence data demonstrated that Nephelolejeunea is paraphyletic with respect to Siphonolejeunea. Nephelolejeunea and Siphonolejeunea are, therefore, merged and, as the latter name has priority, new combinations in Siphonolejeunea are made for 10 species. The valid publication of the name Austrolejeunea is re-evaluated and we conclude that both Siphonolejeunea subgenus Austrolejeunea and Siphonolejeunea olgae were validly published in 1963. Siphonolejeunea bidentata is reported as new for New Zealand on the basis of a collection from the Wairarapa, a new species, Siphonolejeunea raharahanehemiae, is described on the basis of recent collections from Te Paki, where it grows on the twigs of Metrosideros bartlettii (Myrtaceae), and we provide a revised key to species of Siphonolejeunea. The significant conflict in signal between nrITS and chloroplast markers associated with the relationships of Cololejeunea angustiflora, which chloroplast sequence data suggest may not be grouped with the rest of Cololejeunea, is another interesting result from the phylogeny. The relationships of Cololejeunea angustiflora and its allies warrant further investigation.","PeriodicalId":55416,"journal":{"name":"Australian Systematic Botany","volume":"33 1","pages":"311 - 326"},"PeriodicalIF":1.6,"publicationDate":"2020-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1071/SB19035","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47134951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Utricularia dichotoma Labill. complex is a morphologically and ecologically variable group of closely related taxa with a mostly temperate distribution across New Zealand, New Caledonia and Australia. Taxonomic boundaries within the complex have been the subject of speculation, with several previously recognised species being synonymised after a nomenclatural revision. We sampled 296 populations representing all known taxa; 223 accessions were used in the full phylogenetic analysis based on two non-coding chloroplast regions (rps16, trnD–T) and two nuclear ribosomal spacers (external transcribed spacer, ETS; internal transcribed spacer-1, ITS-1), whereas the remaining accessions were identified by using ITS-1 barcodes. We found strong support for a paraphyletic U. dichotoma, with accessions matching the type material of that name grouped within a polytomy that includes clades containing accessions of U. monanthos Hook.f and U. novae-zelandiae Hook.f. Specific statuses for five recently described species previously included in U. dichotoma s.l. do not fall within this polytomy, nor do the two species U. oppositiflora R.Br. and U. speciosa R.Br. resurrected from synonymy of U. dichotoma. All sampled accessions from New Zealand form a single clade within U. dichotoma as recognised here. We here propose that seven clades recovered here be recognised as subspecies, and describe eight new subspecies, including two new combinations. We also propose that the monophyletic clade sister to U. beaugleholei Gassin be assigned to subspecies rank under that name.","PeriodicalId":55416,"journal":{"name":"Australian Systematic Botany","volume":"33 1","pages":"278 - 310"},"PeriodicalIF":1.6,"publicationDate":"2020-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1071/SB19003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43209828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The taxonomic limits of Styphelia (Ericaceae, Epacridoideae, Styphelieae) have been contentious since the genus was first described. At one extreme, it has been circumscribed so broadly as to include most epacrids with drupaceous fruit, at the other, to include only those species that also have long-exserted anthers and styles. Recent molecular phylogenetic analyses have indicated that while all previous circumscriptions of Styphelia are non-monophyletic, a large clade (the Astroloma–Styphelia clade) is consistently well supported. This clade comprises Astroloma, in part (i.e. section Stomarrhena sensu Bentham), Coleanthera, Croninia, Leucopogon, in part (i.e. section Pleuranthus sensu Bentham) and Styphelia sensu Bentham. On the basis of those analyses, we here recircumscribe Styphelia phylogenetically to include all species belonging to the Styphelia–Astroloma clade. The 146 taxa occur mostly in Australia, with smaller numbers in New Zealand, New Caledonia (1 species extends to Fiji and Vanuatu) and Malesia. An additional 74 phrase-named taxa belong to this clade, including 70 from Western Australia and 4 from eastern Australia (all other Australian states and territories). The Styphelia floras of Western Australia, eastern Australia, New Caledonia and Malesia are each endemic or nearly so; 1 species (S. nesophila (DC.) Sleumer) is shared between New Zealand and eastern Australia, and 2 species (S. cordifolia (Lindl.) F.Muell. and S. woodsii (F.Muell.) F.Muell.) are shared between Western Australia and eastern Australia. An amended diagnosis of Styphelia is provided, new combinations are made for 25 taxa, and new names published for another 9.

A species of a closely related genus Adelonema, namely A. crinipes, was included in the study to clarify the results. Our results indicated notable differences in the species of the subgenus Meconostigma, mainly in terms of the presence (and variations) of a lobed stele, whereas the cylindrical stele stood out among the common characteristics in P. subg. Philodendron, P. subg. Pteromischum and the related species A. crinipes. Moreover, the characteristics shared by P. subg. Philodendron and P. subg.
